IMPRVED APPARATUS FOR GENERATING CARBONIO-ACID GAS.

Specification forming part of Letters Patent No. 47,205, dated April 11, 1865.

To all whom t may concern,.-

Be it known that we, PETER HINKEL and FREDERICK HINKEL, both in the city, county, and State of New York, have invented a new and improved apparatus for generating carbonic-acid and other gases, to be adopted for mode of preserving beer, preparing of mineral waters, 85e.; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

To enable others familiar with gas-generating to make and use our invention, we will proceed to describe its construction and opertion.

0n reference to the accompanying drawings, which form apart of this specification, Figure I represents a vertical section,and Fig. 1l a plan view, of our apparatus.

A and B are vertical cylindrical vessels, conically formed on their bottom and held in an iron frame or any other suitable bearing. 0n the sides of obth, about threevfourths of their height, are the llingoritices o and o', and on the bottoms the outlet-openings h and k', all having suitable stopings fitted to them, as may be seen in the accompanying drawings, A being the gas generator and B the Washin gvessel or purifier. The interior of both is connected by means of the pipe a, which leads from the top of A to the bottom of B. A, the gasgenerator, is lined in the interior with lead so as to resist muriatie or sulphuric acid. The longlnecked jar l, or the receiving-Vessel for the marble or the resp. carbonate, is made ot' the same metal, with many holes on the bottom, so as to allow `the muriatic acid, &c., to go through. rEhe cover K of the generator A has in its center an opening of about two and one-halt` inches diameter, through which the neck ot' the jar l may pass easily up and down-` ward. The neck of this jar bears on its top end the flanges g and g', (the latter being tted movable over the irst,) and the hollow screw s, having a stoping, as may be seen iu the aocompanying drawings, and a sliding bar, m, attached to it. By this arrangement and by means of the ange p and screws a ot' the center-piece of cover K an air-tight connection ot' the rubber hose r, between the cover K and the neck of jar l, can easily be formed. The

cover K bears two strong wires, `w w, which both are connected with the already-named sliding bar m, attached to screw s, which are intended to allow a regular up-and-down` ward movement of the jar L.

In order to prevent a ball-like up-blowi'ng ot' the rubber hose r, we cover thesame with cloth or leather, and that it by the downward moving may fold easier and better together, we prepare it in a folded shape. i

It is evident that any other air-tight exible material may be suiteable under circumstances. The pipe a has over cover K of vessel A a valve, V, by which a streaming over of the water in vessel B to vessel A will be prevented.

The cover K of vessel B bears, besides the connection-pipe a, the pipe b and the ask f, with the outlet-pipe c. The pipe b leads almost to the bottom of the flask f. By this and by means of the ioat and valve ot' flask f all overfiown water of vessel B will be led back to the same. i

The screws a: and x ot' vessels A and B will serve to fasten the covers K and K', properly underlaid with rubber or lead packing, &e., air-tight, to A and B. i

To operate with this our improved appara tus, it is only necessary to till the vessel A with a mixture of about 011e part acid (muriatie acid) and one part of water, and the vessel B with pure water, by means of the orifices g and g, and stope the same. Then the leaden i tion. The moment the acid comes in contact with the marble the latter is decomposed and carbonio-acid gas is disngaged, which, as it gradually fills the jar l, raises the same until it is out ot' the acid liquid. The consequence of this is that the liberation otl the gas immediately ceases. Onturning the cock c ot' the flask j' the gas is permitted to escape from the generator A in the pipe a and upward through the water in vessel B, Sac., on which way it is deprived of all impurities. As the gas escapes the bellows-formed rubber hose r folds again, and thus the jar l, attached to it, must sink with it; the acid again enters the jar and attacks the marble as before, the generation 0f the gas being continued as long as it is permitted to escape out of vessel B.

When it is necessary that the gas should be subjected to a greater pressure than that occasioned by the Weight ot the jar l with the requisite quantity of marble it contains, the additional pressure may be obtained by affixing the rubber hose r and the cover K of the generator with a spring, &o.

It will thus be seen that not only anyamount of gas can be liberated Without loss which causes from the manufacture of a greater quantity ot' gas than is desirable to use, but thatit may be subjected to any amount of continuous pressure desirable, however so small the quantity of gas may be.

It will also be seen that, although we have described our improved apparatus as applied to the manufacture of carbonic-acid gas, it may be used in a like manner for generating other` gases, by substituting other materials for the muriatic acid and marble-as, for instance, hydrouoric acid or sulphurated hydrogen gas, or sulphurous acid or hydrogen gas may be generated by the apparatus. It should be understood, however, that the lining ot' the generator and the material of which the jar l is made or composed must be varied to suit the. materials from which the gases are generated, and, of course, in such cases the Washingvessel or puritier B must be lined in the interior with the corresponding material.

Having thus described fully our invention, We claim for us as new and desire to secure by Letters Patentl. The long-necked jar Z, hose r, or their equivalents, and the air-tight connection between them and the cover of a gas-generator, A, as described, or its equivalent.

2. The sliding bar m, the Wires u: w, or their equivalents, and the connection of them with jar l, hose r, and cover K, in the manner full y described, or its equivalent, and for the purpose set forth.
